Backpack interposer
The Backpack interposer module's schematic and board, KDINT001 revision 1.0, viewable here and downloadable as KiCad sources.
What it is
The backpack interposer is a passive adapter: a 2.54 mm header on the Kode Dot side and a 0.8 mm board-to-board connector on the module side, with every signal routed straight through. It is what lets the Mesh and F*CK modules stand upright. Two copper layers. The module's page, modules/overview, says what it does and which GPIO is which; this page is the design itself.
Revision 1.0, released 2026-09-14, drawn in KiCad 10. Symbols, footprints and 3D models come from Kode's shared hardware library.

The schematic sources, as published here. Open the .kicad_pro in KiCad 10 with the sheets beside it. The cover sheet's embedded fonts were removed from these copies and the project's text variables written in; the design is unchanged. The board layout is not published.
